Autism Diagnostic Observation Schedule
(ADOS)
What is an ADOS?
An ADOS is a standardised way of assessing communication, social interaction, play and imagination skills; which may include:
- Body language
- Eye contact
- Use of gestures
- Imagination
- Story-telling
- Use of language
- Repetitive behaviours
- Sensory seeking behaviours
It may be used as part of the assessment for children and young people who have been referred because of possible Autism. The ADOS is part of an overall assessment process carried out by a multi-disciplinary team.
What happens during the ADOS?
The practitioner will engage the child in a number of developmentally appropriate play-based activities. For younger children and those with limited speech, it includes games, looking at books and pictures. The practitioner will be observing how your child responds and interacts with them during the activities, this includes specific behaviours and signs related to the diagnosis of autism.
How long does the ADOS take?
Your child will be in the ADOS room for just under an hour, after which they will continue to play in a different room while the practitioners discuss the findings. Feedback will then be given to parents. In general, the whole process can take two hours.
Who is present during the ADOS?
Usually there are two practitioners present. One will be taking the child through the activities, the other will be observing and making notes.
Can I stay with my child?
Yes, one parent/carer can be present throughout the ADOS in the room. During the assessment, to ensure we have a reliable and accurate assessment, we ask that you only respond if your child approaches you. Therefore, it is important that you do not join in with the play or activities such as telling your child what to do or giving your child any instructions.
What if my child does not want to play and engage?
Don’t worry, we understand that every child is different, and want to reassure you that whatever your child does on the day, it will help us to better understand them. This is also why we have a number of different ways of gathering information as part of the overall assessment process.
We understand that this is an important appointment for you and your child. It’s normal to feel anxious, because you want to do the best for your child. Don’t worry we will be there supporting you and your child through every step of this appointment and the overall assessment process.
